Cotypist is a polished local AI autocomplete tool for Apple Silicon Macs. It runs a purpose-built on-device model, predicts your next words passively as you type, and learns your writing style over time - no cloud, no account, no audio leaving the machine. Its main limits: Apple Silicon Mac only (no Windows, Linux, or Intel Mac), no voice dictation, no active AI command layer, no meeting transcription, and a 100 words/day cap on the free tier with subscription-only pricing (no lifetime option). If any of those are the constraint, here are the best alternatives - ranked with honest pros and cons.
